ISR that are normally clear. RST is one, though in some overflow cases
it can be set. RDC is only set when a remote DMA is finished from the
memory mapped memory to the transmit rings, which we poll fore in the
code with ED_LOCK around the operation that would set it.
This can later use this to determine the TSC frequency like is done with
VMware, instead of using a DELAY loop that is not always accurate in an VM.

KVM clock shares the same data structures between the guest and the host
as Xen so it makes sense to just have a single copy of this code.

The changes unrelated to the bug in r277948 made
the code very difficult to understand to both
coverity and regular humans so take a step back
to something that is much easier to understand
for both and follows better the original code.

With the previous layout, the majority of the release
notes were categorized under one main "What's New"
section, which in addition to making the page difficult
to parse relevant bits, also had a few rendering issues,
such as 'Note' blocks visually not appearing as if they
pertain to a particular change.
This change removes the "What's New" section, integrating
it with the introduction. In addition, each section now
provides a brief description of its contents, broken down
further into a subsection for each "topic", making it much
easier to find a specific topic in the page.
